CLOCK-BELL.

SPECIFICATION forming' part of Letters Patent No. 276,456, dated April 24, 1883. Application filed September-4, 1882. (No model.)

To all whom t't/may concern Be it; known that I, GEORGE E. NORTON, of New Haven,in the countyr of New Haven and State of Connecticut, have invented a new Improvement in Clock-Bells and I do hereby declare the following, when taken in connection .with accompanying drawings and the letters of reference marked thereon, to be a full,clear, and exact description ot' the same, and which said drawings constitute part of this specication, and represent, in

Figure l a front View of a cathedralbell 5 Fig. 2, a front view of the central-stroke bell.

This invention relates to an improvement in the manufacture of wire bells such as used for clocks. v

` Heretofore thesebells have been made from wire, coiled into the required shape, and then the end by which they are to be secured soldered, brazed, or otherwise secured to a collet of suiicient size to attach the bell to its post. In this construction Ot bell the tone of the bell is more or less qualified, according as the attachment is more or less perfect, and in any case the wire frequently breaks at the collet, as the bell is necessarily struck near that point.

The object of my in'i'ention is to construct the collet and bell in one and the same piece, whereby the difficulties existing in the previous constructions will bey-avoided; and the invention consists in a coiled bell having the collet formed in one and the same piece therewith, as morefullyhereinafterdescribed. Theshape of the collet depends upon the kind of bell. For the `more common class of clocks the collet A is at thecenter, as seen in Fig. 2, while for the better class, commonly called cathedral-bells, the collet is at the outer end of the coil, as seen in Fig. l. I take a piece of steel of sufticient extent to produce the collet and bell complete, and from the collet l draw out the metal to a sufficient length, to produce the coil B required, strengthening the bell at the collet by a gradual reduction from the collet outward, as at a, so that aconsiderable extent of metal isleft near the collet. After the metal has been drawn down itis coiled according as the bell is for a cathedral-bell, as seen in Fig. l,or central-stroke, as seen in Fig.2. In drawing the wire may be left round, square, dat, or any desirable shape, and after it has been properly drawn out it is coiled into the required shape for the bell in the usual manner for coiling such bells, and is tempered also in the usual manner, the collet bored for the attachingscrews also in the usual manner. This drawing down of the metal is best done in what are known as reduciiig-machines7-that is, rapidly-vibrating hammers, between which the metal to be drawn is introduced. By this construction the collet becomes an integral part of the bell, and therefore does not qualify the tone as when made of a different metal and attached to theend ofthe wire, and being strengthened in drawing at the junction with the collet the liability to break at that point is avoided. The bell is also of a better quality, as the ha|nmering tends to rene and consolidate the metal more perfectly than by the usual drawing process by Which wire is reduced.

I claim- The herein-described bell, consisting of the coil drawn from the coliet and in oneand the same piece of metal therewith, substantially as described.
